There isn't enough change here to warrant the effort. It just isn't very exciting.
Novel viewing out windows, but cannot see far, trades issues of sun on work areas in the office on a clear day in winter.
I like the design concept used in this submission. Installing new steel posts could be a little costly, but definitely could be done if necessary. I like how the designer incorporated the use of some of the existing wrought iron into the design. This is a very clean and inviting design. Just enough detail to give the building a updated and modern look.
